This elongated ear pendant (sochi or so-byis) would have been worn suspended from the left ear by a Tibetan government official as an insignia of rank. See Jane Casey Singer, Gold Jewelry from Tibet and Nepal (New York: Thames and Hudson, 1996), pp. 100-101, nos. 30-31. It has a C-shaped brass hoop, below which are bands of granulated gold beads alternating with inlaid turquoise, which was believed to promote good health. In the middle is a piece of colored quartz (in place of the more customary pearl). The lower terminal is a faux-turquoise glass drop held by a gold collar. Comparable Tibetan ear pendants were sold by Michael Backman Ltd, London.
